Different president, different circumstances...
Even while Obama was doing things contrary to the Constitution, only the most extreme of the opposition were screaming for resignation or impeachment. Plus his way of dealing with people was more traditional, politeness and even more polite lies.
Trump makes even his most ardent supporters occasionally flinch, but it has gotten to the point that everything he says is horrid and vile according to the most of the party in opposition. Your statement that support of Trump (which most believe include his policies) shows one to have "no class or morals or integrity. You are a lost cause with no compassion for humanity." is the sort of blanket statement that increases the divide in the US and solves nothing.
There is no evidence that the President is a racist. There is a lot of evidence that he is not a person that watches every word he says or that he sugar coats much. He is not a typical politician of any party.
You have every right to bad mouth the President, oppose all of his policies, but when you say that support of the President and/or his policies makes one a "lost cause" or worse, you are full of your own hate.
